Thoughts from you scientists on this.

[Graybeard58]

I wish that they would give a little more detail as to why it makes an engine more fuel efficent.

It'd have to be something you felt good about building an engine for and the ordinary yuppy these days can't even add oil to his own car, much less build engines.

Cryo treating rifle barrels makes them nearly as hard and smooth (and easy to clean) as if they were chrome lined. It would have to eliminate a lot of the friction in a normal sort of internal combustion engine.

Lots of interest from many areas including
brass musical instruments, softball bats, tools, motor sports
gun barrels, etc.

Discussion on use in music
Sounds interesting

"Today we can use a process called Cryogenic Resonance Restoration TM that not only duplicates the aging process but in many ways has improved it. CRR TM is a dry process where instruments are placed in a specially designed and insulated chamber that is computer controlled to hold temperatures below - 325 F. The process itself is very gentle, with changes in temperatures occurring at approximately 1 degree per minute: it will not effect lacquer or plated finishes. By cryogenically processing instruments, residual and compressive stresses from the dislocation of the metal's structure is reduced. The metal itself becomes a better resonator by making its grain spacing smaller. This allows resonance to travel more freely through the metal.

Figure one: metal lattice - atoms of alloy metals such as brass line up imperfect rows stacked densely on top of each other. When the instrument is hammered & bent into shape, the atoms can get pushed apart ( stressed ) or whole planes can get knocked out of alignment ( dislocation ), as shown left. Freezing the instrument reduces the residual stress in the metallic lattice. The metals used in musical instruments are improved by the cryogenic process through improving the homogeneity of the crystal structure, reducing gaps, and dislocations caused by this forming process.

Sound quality improves because the resonance character is not lost by dampening stress. The harmonic structure present before the process is enhanced and musicians often find a better core to their sound with a more even timbre throughout; dynamics and pitch center, as well as the efficiency, can also be improved. What Cryogenic Resonance Restoration TM will not do is transform a poorly made or designed instrument into a good instrument, but it can make a good instrument even better."

They laughed when I wound up my shaver!

You too can get 200 MPG!

Does this mean Ted Williams never gets gas?

Racers have picked up on David's trick of cryogenically freezing car parts. It is now widely accepted among NASCAR and Indy-car racers.

gives new meaning to freezing your nuts off

[Cobra64]

This sounds like another unrealistic dreanm.

What is the cost for the liquid nitrogen. or the means to produce it?

I have some Free Zing in my engine, but it is more like Cea Zing.
